Everyone wants something of their own. But understand this. I don't want to and won't add sex scenes, by way of example - "Let's fuck!". There has to be a story, that story must somehow fit my vision of the story and be supported by something. You can, of course, offer your own ideas, but that doesn't mean they will be fulfilled.
I have a little outline of what will happen at the beginning and the end of the story. Little by little I fill in the gaps with my ideas or expand on someone else's here, someone else's ideas even coincide with my ideas.
